Description
Technical field
The present invention relates to technical field of civil engineering, more particularly to a kind of raising blast funnace hot blast stove furnace shell splicing accuracy and
The installation method of speed.
Background technique
Traditional blast funnace hot blast stove furnace shell assembly jig mainly has two kinds of shapes of steel assembly jig and cast-in-place concrete assembly jig
Formula.Assembly jig needed for newly-built blast funnace hot blast stove on-site consolidation generally uses cast-in-place plank frame.
But plank frame concrete assembly jig pours that area is big, thickness is usually partially thin that (thickness increases to concrete
Consumption influences big), therefore board-like concrete assembly jig concrete consumption is not only larger, effect is not ideal enough, and furnace shell is assembled
Stage is easy to happen fracture, influences furnace shell splicing accuracy, " rice " shape large-sized direct-burried item of traditional board-like concrete assembly jig
Shape built-in fitting length is long, and installation level precision is not high.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of raising blast funnace hot blast stove furnace shell splicing accuracy and speed
Installation method has the advantages that bearing capacity is high, deformation is small using beam type cast-in-place concrete assembly jig, and assembly jig is installed detachable
The direct-burried bar shaped built-in fitting that the installation horizontal accuracy of large-scale bar steel plate is more traditional greatly improves.
The technical solution adopted by the present invention to solve the technical problems is: it is assembled to provide a kind of raising blast funnace hot blast stove furnace shell
The installation method of accuracy and speed, comprising the following steps:
(a) the basic beam forms and adjusting template absolute altitude suitable for reading of hot-blast stove assembly jig concrete foundation beam are installed；
(b) hangs muscle for being used to fix perforated bolt built-in fitting is rested on into the suitable for reading of basic beam forms and fixed；
(c) perforated bolt built-in fitting is installed on the inside of basic beam forms and is connected with hangs muscle, and is worn in the upper end of hangs muscle
Bolt and nut can accurately adjust the installed height mark of perforated bolt built-in fitting by rotating nuts；
(d) in the casting process of concrete foundation beam and annular girder, reserved joint bar is uniformly inserted on foundation beam surface；
(e) the bar shaped steel that the section for connecting furnace shell assembly jig is in " rice " font is set on the outside of concrete foundation beam
Plate is bolted between the both ends of the bar steel plate and corresponding perforated bolt built-in fitting；
(f) pressing plate muscle is added among bar steel plate, bar steel plate is pushed down and aligned, and the levelness of bar steel plate reaches furnace
After shell splicing accuracy requires, pressing plate muscle is mutually welded with corresponding reserved joint bar；
(g) assembly of progress furnace shell, assembly to vault, because furnace shell radius substantially becomes smaller, when existing assembly jig is not able to satisfy,
Pressing plate muscle and bar steel plate are successively cut off in sequence；
(h) after the furnace shell assembly jig assembly dismounting on the outside of concrete foundation beam will be mounted on, it is transferred to concrete foundation
Installation on the inside of beam, erection sequence are detailed in above-mentioned step (e) and step (f)；
(i) furnace shell assembly finishes, and removes bar steel plate, may be reused.
As a kind of supplement, billet is installed to increase bearing area on the downside of the both ends of bar steel plate in step (e).
The utility model has the advantages that the present invention relates to a kind of installation method for improving blast funnace hot blast stove furnace shell splicing accuracy and speed, compared with
Traditional board-like concrete assembly jig, beam type assembly jig concreting amount largely reduce；The ironware of the assembly jig is by traditional
" rice " font pre-embedded steel slab is changed to bolted detachable member, and steel using amount reduces half, and may be reused；It is new assembled
The bar steel plate horizontal accuracy of platform is high, is conducive to furnace shell quick-assembling, construction consumptive material is greatly decreased, assembly jig installation accuracy is high,
Tool-type steel member can be recycled, and furnace shell assembly jig construction cost can reduce by 60% or more compared with traditional method.
